That for sure. But I don't think the situation is exactly the same, to 
be honest. Note, I don't know what exactly "undesignated" means, I 
understand you already used that approach, thus don't hesitate to try it 
here too!

Take your time (no pun intended ;) you may want to disable temporarily 
the auto with a FIXME comment.
